Precision T3500 PCIe specs confusion.

Question

Hi,

I would like to fit a USB 3.0 or 3.1 PCIe card to get faster write times than my current eSATA external HDD set up. I also want to get one that is appropriate for the speeds my motherboard will allow. However, I don’t understand the PCIe specs.

The board itself is a 0XPDFK and has two x8 slots that I understand are wired as x4, one of which I think will be suitable for the card. Next to one of these slots “SLOT1 PCIe2 x4” is printed onto the motherboard. On the other “SLOT1 PCIe x4” is printed. However, in the service manual it says the following:

Bus type

PCI 2.3
PCI Express 2.0 (PCIe-x16)
PCI Express 1.1 (PCIe-x1)
SATA 1.0 and 2.0
USB 2.0
eSATA

Bus speed

133 MB/s (PCI)
x1-slot bidirectional speed - 500 MB/s (PCI Express)
x16-slot bidirectional speed - 8 GB/s (PCI Express)
1.5 Gbps and 3.0 Gbps (SATA)
480-Mbps high speed, 12-Mbps full speed, 1.2-Mbps
Low speed (USB)

Does this mean the x8(x4) slots are PCIe 1.1 at x1 (one lane?) Doesn’t this contradict “PCIe2 x4” that is printed on the board?

According to some geeks I’ve talked to, you can put a pcie3 gpu in a pcie2 slot and the slot will just slow it down to the pcie2 speed.
